Missing Windows under RA_CNN_caffe folder

[by5262]

Downloaded the relevant file, when compiling caffe will prompt error LNK2001: Unresolved external symbol "public: __cdecl caffe::SolverRegisterer::SolverRegisterer(class std::basic_string<char,struct std: :char_traits,class std::allocator > const &,class caffe::Solver * (__cdecl*)(class caffe::SolverParameter const &))" (??0?$SolverRegisterer@ M@caffe@@qeaa@AEBV?$basic_string@DU?$char_traits@D@std@@v?$allocator@D@2@@std@@P6APEAV?$Solver@M@1@AEBVSolverParameter@1@@z @z) D:\caffe\Recurrent-Attention-CNN\RA_CNN_caffe\windows\classification\adadelta_solver.obj classification error.
Is this because I don't have a related Windows file?
